As I have mentioned elsewhere on HN, one of the purposes behind our new startup is to help entrepreneurs like you find great co-founders: we ensure that you only get connected with the most qualified candidates for your purposes, immediately. This means that you don't have to spend weeks filtering through hundreds of resumes from people who never even read your job description. And, you don't waste time interviewing totally useless candidates who shamelessly over-marketed themselves.
We're not quite ready yet, but if you sign up you can give it a shot! venturocket.com
